(Midpipe) Exhaust gasket material- off the counter stores?
 

Looking for sheets of exhaust gasket material I can buy off the counter at an Advanced Auto Parts, AutoZone, or Pepboys. Something that will obviously hold up to our EGT. No, I can't buy pre-made flange gaskets and prefer not to order because I need it ASAP.

All I've found are these:
Gasket Material | AutoZone.com

Advance Auto has a turd of a website, so I can't link the gaskets by FelPro and Mr. Gasket I've found.

Vibrant makes Pre-mades.I just got a 3 inch flange gasket.(looks like an Eye,sort of thing)
If you use the roll,then you need the stuff that has the "metal" on both sides and the fiber in the middle.

Went to a local performance shop and they had a 3" Vibrant 3 bolt flange gasket. Wasn't even close to fitting the midpipe's flange. The gasket was way too small and bolt areas were wrong. Same goes with their two bolt gasket for the other side.

I also went to AutoZone and the rep wasn't so helpful. He looked up a few gasket sheets online and from what I can tell, they won't hold up to 2 miles of driving heat.

I have a MazSport midpipe (for an RX-8), and the flanges are all sorts of weird.
